Fire stopping for businesses in Greenrigg

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Fire stopping in Greenrigg, done properly

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. If you’re dealing with fire stopping installed outside its tested range and openings left by services added after handover, we can help, whatever the surface. Looking for mastic applicators who cover Greenrigg? We’ve been sealing commercial buildings since 2005.

In smaller Scottish places like Greenrigg, buildings with fire-resisting walls typically include schools, care homes, hotels and health centres. Those penetrations are closed with the product the specification names, built up as tested.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Building owners, agents and FMs in Greenrigg

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Approving the work on behalf of building control
  • Plastic pipes whose detail calls for a collar or wrap
  • Fire risk assessments, a job for a competent assessor

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we’ll tell you honestly.

Where we work in Greenrigg

  • Small duct penetrations where the tested detail allows
  • Linear gaps at wall heads
  • Joints between fire-resisting walls and floors
  • Cable penetrations
  • Pipe penetrations
  • Service gaps in risers

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. For work around Greenrigg, we aim for one trip, so photographs, sizes and a full list matter. External joints need a dry spell as well.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Have the specification and drawings to hand
  • Point out parking and an unloading spot
  • Let building users know which areas are affected

Advice

Maintenance after handover

To get the most from the new sealant:

  • Arrange inspection before areas are covered up
  • Settle who seals which penetrations at the start of a project
  • Check with the data sheet before painting over fire sealant
  • Keep general-purpose fillers away from compartment walls

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.

Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.

Leave it or put it right?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these, and the other benefits follow. Renewing every failing joint on one visit is the sensible approach for a place like Greenrigg. Send photos and we’ll quote for everything together.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Different surfaces, different methods

Small ducts

Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork usually needs a different solution set by the designer and we flag that rather than guess.

Risers and ceiling voids

Voids hide a lot of unsealed openings. We follow your schedule area by area, and note anything we find that isn’t on it.

Fire stopping in Greenrigg: the local picture

Under the Scottish non-domestic Technical Handbook, clause 2.1.14, penetrations should be fire stopped to at least the wall or floor’s fire resistance duration, and products should be tested for their end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

Holiday works at schools like Armadale Academy often leave service openings to seal before pupils return. On estates like Harthill Industrial Estate, 0.9 miles to the west of Greenrigg, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. Hospital estates such as Tippethill Hospital (2.3 miles north-east of Greenrigg) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Greenrigg is about 2 miles west of Whitburn, in West Lothian. Commercial clients in Greenrigg use us for work on service penetrations. Greenrigg is one of 55 places we cover in West Lothian. Our Glasgow page has more on work in that area, about 21 miles away.

Greenrigg: questions and answers

Is a smaller place like Greenrigg outside your area?

Not at all: smaller places are covered as well as towns. Our area covers all of Scotland, cities, towns and islands alike. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

What do Scotland’s building standards say about service penetrations in Greenrigg?

Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using products tested for their end use. Design sits with the designer and the verifier; installation to the tested detail is our part.

What about RAMS and site documents?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Can staff carry on working while you are here?

Usually, yes. We phase the work so most of the building stays in use.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How do I request a quote?

The quote form is the simplest route, though you can also speak to us on 01277 525 020 or email us. Include photos or drawings if you have them.
